The 19-year-old left Southampton in a world record transfer for a teenager. And Baggies boss Irvine reckons that has led to other clubs pushing up asking prices for players.

Albion tried to sign Aaron Cresswell from Ipswich but pulled out when his price tag rocketed, and the left-back eventually joining West Ham for a fee which could reach £7m.

Then, Aston Villa pulled the plug on a deal that would take their defender Alan Hutton to the Hawthorns.

Liverpool right-back Andre Wisdom and Australia left-back Jason Davidson, who plays for Dutch side Heracles, are on Irvine’s radar now.

He said: “When you look for full-backs now, the prices have changed as a result as what happened with Luke Shaw. Players are worth a lot more than before and that makes it more difficult for us. We need several more new faces in.”
